acceptable addendum?

[osutennisguy04]

I'm not too sure on how this works, but I am thinking about the idea of writing a GPA addendum. During the first quarter of the year I received a 4.0. At the end of the quarter my grandmother passed away (primary guardian) and I fell into a depression, the following two quarters I received a 3.5, and 3.2. I started counseling and it really helped out and I know I will be in good condition during this fall quarter.

I am afraid that this decrease will be looked upon negatively. Addendum a good idea? Any ideas on how to approach it

thanks
